Maximum Quantities: C4B, in its sole discretion imposes a maximum quantity per ISBN, per account, and/or per IP address. Your seller cart will indicate how many of each book C4B will purchase, indicated by "MAX=" for each book in your cart. After entering ISBNs, you can change quantities by clicking on "View your seller cart." If you are a reseller and/or have large numbers of books above C4B's allowable maximum, please send us an email and C4B's Inventory Management team will correspond with you. Additional copies of books sent to C4B over and above the allowed maximum quantity will NOT be accepted.*

*Items not accepted by C4B will only be shipped back to the Seller at the Seller's expense. Items not accepted will be held for 14 days; after that time, these items will be recycled, donated, or used to support the community and environment at C4B's discretion. C4B will post a notice of any deductions for items not accepted on the seller's account within 2 business days after receipt. If the Seller would like their unaccepted items returned, the Seller must contact C4B promptly, through email or phone, to provide payment for return shipping costs.

How it works

Following the three step process on our homepage, you start by simply entering the ISBNs of the books you want to sell into the form. Ship your books to us for FREE, and then collect your money via PayPal or check.

On average, it takes 13 days from the time you click "sell my books" to when payment is issued. It can be shorter or longer depending on what shipping method is used, and your proximity to Hillsboro, Oregon. After your books are received, inspected and marked as 'processed', payment will be made. Payment is sent within one business day of 'processed' status.

We buy mostly college textbooks, but sometimes other books as well. View our example 500 list page, which shows
examples of books that we commonly purchase.

Most of the books we purchase have a publication date within the past three years. What we buy can change day by day or week by week depending on resale values, our current inventory, demand, and other factors.

Shipping is always FREE with our pre-paid mailing label that you print right from your computer.

If you do not have a printer, simply contact us to request US Post Office shipping labels to be mailed to you.

Further instructions on FedEx or the US Post Office are provided after you submit your books to be sold. Also, if you need to know where to get a box to mail your books, please read our frequently asked questions.
